CORPORATION 01 DELAWARE AUTOMATIC SOUND ?EPRODUCING INSTRUMENTApplication filed July 15,

The present invention relates to coin-cononic musical instruments; andits object is, generally, to provide such an instrument improved inrespects hereinafter appearing; and more particularly, to provideimproved means for initiating the operation thereof including animproved coin-chute; and further, to provide improved means for movingany desired one of a plurality of record disks to and from the turntableof the instrument; and further, to provide improved means whereby eitherof the records on the opposite sides of the disk may be selected to beplayed; and further, to provide improved means for moving the tone armof the instrument into and out of opera- 1 tam of sald parts,

tive relation with the record disk on the turnto provide improved meansfor effecting the operations of the parts of the instrument in orderedsequence and for reversing the movements of, or for returning to initialpositions, the said parts for subsequent operations of the instrument;and further, to provide improved means for changing the needles carriedby the tone arm and further, to provide improved mechanical connectionsand motion-transmitting mechanisms whereby the parts of the instrumentmay operate in ordered sequence.

These and any other objects hereinafter appearing are attained by, andthe invention finds a preferable embodiment in, the instru- Inenthereinafter particularly described in the body of this specification andillustrated by the accompanying drawings, in which Figure 1 is a rearelevational view of the principal parts of the mechanism of ourcoincontrolled graphophonic musical instrument;

The coin-controlled graphophonic musical instrument illustrated by saiddrawings comprises means for initiating the operation thereof, means forrotating a turntable sup: porting the record disk being played, meansfor moving any desired one of a plurality of such disks to the turntablepreparatory to playing the selected one of either of the records on itsopposite sides and for returning the disk from the turntable, means formoving the tone-arm carrying the recordengaging needle into and out ofoperative relation with the disk, means for effecting the operations ofsuch parts in ordered sequence, means for reversing the movements of; orreturning to initial positions, the said parts for subsequent operationsof the instrument, means for changing the needles carried by the tonearm, and other means more or less subsidiary to the said various meansand contributing to their sequential and positive operations.

In the embodiment of theinvention chosen for illustration by saiddrawings and for detailed description in the body of this specification,the operative parts'are carried by a frame 261 enclosed in a suitablecasing 212 havingvpreferably a glazed front opening through which suchparts and their operation may be seen. A plurality of record disks 214:are contained in the casing any one of which and the record on either ofits opposite sides may be selected for playing. Coin chutes designatedgenerally 215 are arranged side by side adjacent the front of theinstrument, and in operative registration respectively with the recorddisks to be selected for playing. a

The illustrated means for initiating the operation of the instrument andthe operation thereof are as follows (referring now particularly toFigures 2 and 17) Each of the several coin-chutes 215 comprises a fixedportion 216 and a portion 217 swingably mounted at 218 and having ahandle 219 and a coin-receiving opening 220 outside the casing, asparticularlv well seen in Figures 2 and 3. A coin 221 being insertedinto said opening falls in the chutes portion 217 and into heldengagement with the bight 247 of a spring 222 surrounding chute portion217 near its vent 223. This chute portion 217 is now swung inwardly byits handle 219, the upper edge 224 of the coin in such movement strikingthe end 225 of the downwardly extending rib 226 of an arm 227 swingablymounted at 228, and thus swings said end upwardly and out of its lockingengagement with the inner edge 229 of chute portion 217 immediatelybelow the slot 230
